The wait is almost over. Jabari Parker, called by Sports Illustrated as the best high school basketball player since LeBron James, will announce his college destination on Thursday.

"He's still weighing things," his father, Sonny Parker, told ESPN on Tuesday. "I'm his dad. I don't know where he's going to. I could ask him what school he's going to, and he'll say I'm not 100 percent sure. Hopefully, he'll know something by Wednesday night or Thursday morning. It's a mystery to me. He'll make the right decision. We know he'll make the right decision for him."

Parker, a 6-8 forward, is expected to pick Michigan State or Duke although he has not publicly ruled out BYU, Florida or Stanford.

He has called a 4 p.m. ET press conference at Chicago’s Simeon Career Academy. ESPNU will televise the announcement.

Parker had to lay off basketball for five months while allowing a broken foot -- sustained while leading the United States to the FIBA Under-17 World Championship -- healed. He has played only three games this season, and his father said he likely won’t return until the first of the year.

“He's been doing well in practice, but practice is different than games,” Sonny Parker told ESPN. “He has to continue to do his rehab and get his body back. It's about his future in terms of his health. If he can continue to do his rehab and then practice with no contact and then go full practice, he can play. Right now, he's a little ways away."

While Parker was rehabbing and missing during the summer AAU tournaments, scouts were dazzled by forward Andrew Wiggins of West Virginia’s Huntington Prep. Wiggins then pushed up his high school graduation to 2013, and Parker dropped to No. 2 in the recruiting class.

Simeon is pursuing a record fourth consecutive Illinois state championship. He averaged 19.5 points, 8.9 rebounds, 4.9 assists, 3.3 blocks and 1.4 steals a game as a junior.
